Afforestation priority for multiple objectives at national scale: Italy as a case study

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Afforestation is increasingly recognized as a key strategy to address climate change and ecological degradation, offering multiple ecosystem services. However, strategic planning is needed to ensure that afforestation actions are ecologically effective and economically efficient by targeting areas where ecosystem service provision

Suitability of ground-based SfM-MVS for monitoring glacial and periglacial processes [PDF]

open access: yes, 2016
Photo-based surface reconstruction is rapidly emerging as an alternative survey technique to lidar (light detection and ranging) in many fields of geoscience fostered by the recent development of computer vision algorithms such as structure from motion ...

Quantitative analysis of channel characteristics of distributive fluvial systems

open access: yesSedimentology, EarlyView.
ABSTRACT Distributive fluvial systems (DFSs) are characterised by a radial distributive channel pattern in planform and dominate modern‐day sedimentary basins. Where aggradation occurs, such as in sedimentary basins, there is increased preservation potential, and therefore, DFSs are hypothesised to constitute a significant portion of the continental ...

Updating Norway’s glacial lake extents in 2023–2024 using Sentinel-1 & Sentinel-2 data and machine learning

open access: yesJournal of Glaciology
Glacial lakes are increasing in number and size worldwide, posing growing risks for outburst floods. Norway’s last glacial lake inventory used semi-automatic mapping on Sentinel-2 imagery from 2018–19.

Glacier recession since the Little Ice Age: Implications for water storage in a Rocky Mountain landscape

open access: yesArctic, Antarctic, and Alpine Research, 2019
Glaciers have significant influence on hydrology, vegetation, and wildlife in mountainous regions, and are receding globally. To quantify the impacts of sustained glacier loss, we mapped a complete set of glacier areas from the Little Ice Age (LIA) using

Effects of seasonability and variability of streamflow on nearshore coastal areas: final report [PDF]

open access: yes, 1977
General nature and scope of the study: This study examines the variability of streamflow in all gaged Alaskan rivers and streams which terminate in the ocean. Forty-one such streams have been gaged for varying periods of time by the U. S.

Models of ice melting and edifice growth during subglacial basaltic eruptions. [PDF]

open access: yes, 2007
Models of the early stages of basaltic eruptions beneath temperate glaciers are presented that consider the evolving sizes of volcanic edifices emplaced within subglacial cavities.

Improved representation of laminar and turbulent sheet flow in subglacial drainage models

open access: yesJournal of Glaciology
Subglacial hydrology models struggle to reproduce seasonal drainage patterns that are consistent with observed subglacial water pressures and surface velocities. We modify the standard sheet-flow parameterization within a coupled sheet–channel subglacial

Mechanical forcing of water pressure in a hydraulically isolated reach beneath Western Greenland's ablation zone

open access: yesAnnals of Glaciology, 2016
A suite of surface and basal measurements during and after borehole drilling is used to perform in situ investigation of the local basal drainage system and pressure forcing in western Greenland. Drill and borehole water temperature were monitored during

Application of LANDSAT imagery for snow mapping in Norway [PDF]

open access: yes
The author has identified the following significant results. It was shown that if the snow cover extent was determined from all four LANDSAT bands, there were significant differences in results.
